How to Close Your Pool for the Season in Madisonville, TN: A Step-by-Step Guide

August 21, 2025

Essential Tips from Madisonville's Pool Experts to Protect Your Pool Through the Off-Season

As autumn arrives in East Tennessee, it’s time to prepare your pool for winter hibernation. Properly closing your pool protects your investment, ensures equipment longevity, and makes spring reopening smoother. At ORCA Pools & Outdoors, we bring 15+ years of local expertise in pool installation, repair, and maintenance to help you winterize your pool the right way. Here’s your step-by-step guide:


1. Quality Pool Products & Local Advice from Our Storefront

Visit our Madisonville pool supply store at 206 Mill Street, open Monday–Friday 10AM to 5 PM and Saturday 9 AM to 1 PM, for professional-grade chemicals, testing kits, liners, skimmers, filter sand (Mystic White II), AquaSalt, water test kits (like AquaChek), and more. Our team is happy to provide hands‑on support for winterizing products.


2. Test & Balance Your Water Chemistry

Before covering your pool, adjust pH, alkalinity, and sanitizer levels. Whether using chlorine or a saltwater system, balance is key - even in winter. You can bring a water sample for SpinTouch testing at our store for precise, professional results.


3. Shock & Clean Thoroughly

Shock treatment helps eliminate algae and organic contaminants that can bloom under a closed cover. Clean filters and, if needed, replace pool filter sand - that’s something we install and maintain expertly.


4. Lower Water Level Strategically

Bring the water level down to below the skimmer (for frost protection), but not all the way - especially in freeze-prone weather, as overly low water levels can damage the walls or liner.


5. Drain & Store Removable Equipment

Remove pumps, hoses, skimmers, vacuum attachments, and other accessories. Keep them in a safe, indoor place to prevent freeze damage and warping.


6. Winterize Your Equipment

Disconnect, drain, and store or insulate all pool equipment. This includes pumps, filters, and especially salt systems. Drain sand filters and leave the multiport valve set to “Winterize.” Our team can assist with winter-ready sand filter maintenance and other equipment needs.


7. Install a Custom-Fit Pool Safety Cover

A high-quality safety cover protects your pool from debris, reduces evaporation, and safeguards against unwanted entry. ORCA Pools & Outdoors installs custom-fit safety covers from Merlin Industries, designed for both above-ground and in-ground pools.


8. Safety Checks & Final Inspections

Ensure the cover is properly tensioned, anchored, and free of gaps or sagging spots. This protects the liner, equipment, and your family during winter’s freeze-thaw cycles.
